Help with generic FT2232H adapter

[d18c7db]

Hi, I was trying to use your tool with a generic FT2232H breakout board. The board is detected under the "Probe" menu and I can select it, but when I run "JTAGChain" "Get ID" I get "Error: No device found".

The connections are as follows:
FT2232H-ADBUS0 to target TCK
FT2232H-ADBUS1 to target TDI
FT2232H-ADBUS2 to target TDO
FT2232H-ADBUS3 to target TMS
FT2232H-ADBUS5 to GND

The same FT2232H breakout board with same connections as above works in OpenOCD so the TDI/TDO are the correct way around and gets the expected JTAG ID, however for OpenOCD to detect the breakout board I need to use Zadig and install a WinUSB driver whereas for your "JTAG Boundary Scanner" to detect the breakout board I need to install a libusb-win32 (v1.2.6.0) driver.

It doesn't feel like this is a driver issue though, since the breakout board is detected. It feels maybe like a connection issue, this is why I tied ADBUS5 to GND since it is labeled as "Target presence : 0 if target present" in the config.script so perhaps it needs some other connection as well? What else could be wrong?

Please have a look to the "config.script" file, you can change the FT2232 pin assignation and configuration :

Here is the current default configuration :
